Abstract

The invention relates to the field of machining materials, namely, devices for fixing sleeves in plate satellites for equipping machine tools of the type machining center, and improves the accuracy of fixing the sleeves in satellite plates. In the master plate 1, spring-loaded locking pins 4 with conical bases 13 are installed. In the openings 6 of the satellite plate 3 there are bushings 7 with flaps 8 and made in the form of glasses of body 9 with holes 10 for feeding adhesive mass and pistons 11 with handles. 12. Satellite-plate 3 is installed on the master plate 1 and fixed. Bushings 7 with caps 8 are installed in the holes 6 of the satellite plate. The cases 9 are installed in these holes, which, moving in the axial direction, press the sleeves 7 against the end surface of the master plate 1. Then the adhesive mass is poured into the cavity of the housing 9, the piston 11 is installed, which, when the knob 12 rotates, provides filling with this mass the gap between the wall of the hole 6 and the outer surface of the sleeve 7 and the cover 8. 1 3. p.

The aim of the invention is to improve the accuracy of fastening sleeves in the plates of satellites.

FIG. I shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2 (with spring-loaded tapered locking fingers); in fig. 4 - the same with cylindrical locking fingers with slits; in fig. 5 - cylindrical locking pin with slits, general view; in fig. 6 is a sectional view BB in FIG. five.

The device for fixing the sleeves in the plate-satellite consists of a master plate 1 with devices 2 for fixing the plate satellite 3. The locking pins 4 are installed in the holes 5 of the master plate 1, which form a high-precision coordinate grid. In the satellite plate 3 there are threaded holes 6, which also form a coordinate grid of normal accuracy, similar to the coordinate grid in the master plate 1. Holes 6 have bushes 7 with flaps 8 that interact with the base surfaces of the fingers 4. In the upper part The holes 6 have mechanisms for clamping the end surfaces of the sleeves 7 to the base surface of the master plate 1, consisting of a housing 9 shaped as a cup with holes 10 in its end surface for feeding the adhesive mass and installed in the housing Porsch 11 with a handle 12. Fingers 4 can be made with conical 13 or cyindric 14 clamping surfaces. The base surfaces 14 have starting chamfers 15 and radial slots 16. The holes 5 in the master plate 1 are tupic, the springs 17 and the caps 18 are mounted in the lower part.

The device works as follows.

The satellite plate 3 is mounted on the mass plate 1 and fixed by the device 2. The sleeves 7 with the covers 8 are installed in the holes 6 of the plate satellite 3. After this, the cases 9 are mounted in the holes 6, with which the sleeves 7 press their lower end surfaces to base plane of the master plate- 1. The lower edges of the walls of the openings of the sleeves 7 interact with the conical surfaces of the 13 fingers 4, which move along the axis, compressing the springs 17, which abut their opposite ends against the lids 18. Then the housing ca 9 adhesive mass is poured and set por- schen 11. By rotating the knob 12 is moved

Porschen 11 along the axis. At the same time, the adhesive mass through the holes 10 fills the gap between the wall of the inner surface of the hole 6 and the outer surface of the sleeve 7 and the lid 8.

In the case of using fingers 4 with cylindrical base surfaces 14, the sleeves 7 are pressed against the base plane of the master plate 1 as described. The lower edges of the walls of the openings of the sleeves 7 interact with the front chamfers 15. In this case, the elastic sections of the finger 4 formed by the slots 16 are deformed. The diameter of the surface 14 changes and the surface 14 enters the opening of the sleeve 7 without a gap. The filling of the gap with an adhesive mass is produced in the same way as described.

After the glue joint is polymerized, the grit 11 is removed from the casing 9, which, in turn, is removed from the plate of the satellite 3. Then the plate of the satellite 3 is uncoupled and removed from the master plate 1.
